MOLD.

Specification of Letters Patent.

Patented Apr. 5 1910.

Application filed June 12, 1909. Serial No. 501,730.

To all whom it may concern:

Be it known that I, PETER HALL ALLISON, a subject of the King of GreatBritain, and a resident of Torrington, in the county of Litchfield andState of Connecticut, have invented a new and Im roved Mold, of whichthe following is a full, clear, and exact description. j

' The invention relates to molds used for casting ingots, such as brassbars, to be subse uently rolled into sheet or other form.

he object of the invention is to provide a new and improved mold capableof being opened. and closed without ta ing up much floor space, andarranged ,to prevent the formation of fins and to allow convenient andquick removal of the casting irrespective of any change in the membersof the mold owing to expansion and contraction.

For the purpose mentioned, the mold is formed of two mold members, hi edtogether at one side, to allow of swinging the mold open in a lateraldirection.

Figure 1 is a side elevation of the mold; Fig. 2 is a transverse sectionof the same; and Fig. 3 is a sectional plan view of the same.

The rear and front :mold members A and B are made approximately L-shapein cross section, and the rear member A is provided with a forwardlyprojecting bottom A forming the bottom of he mold. On one side of themold memb rs A and B are formed the hinge eyes C and D, engaged byvertically disposed alined pintles E, to permit of swinging the frontmold member B toward and from the rear moldmember-A on closing or openinthe mold. The center of the hinge, forme by the lugs G and D and thepintles E, is somewhat forward of the adjacent side of the rear moldmember A, as plainly indicated in Fig. 3, so that the L-shaped moldmember B can be readily swung into a closed position against the whencasting the in ot in the mold. Each of the joints F,'F', is formed, byprovidmg a right angled'corner in one member, engaging acorrespondingly-shaped rabbet on the other member, as plainly indicatedin Fi s. 2 and'3.

K locating the axis or center of the bin e in t e manner described,,itwill be readi y seen, by reference to Fig. 3, that the mold member B canreadily swing into closed or open osition without danger of binding atthe joints F, F and F, at the same time insuring proper seating of thejoint members to prevent leakage and the formation of fins when pouringthe molten metal into the mold. When doing this, the mold members arepreferably locked m a closed position by suitable clamps G, as indicatedin the drawings. After the casting is made the clamps G are removed andthe member B is swung.

open in a lateral direction, so that the casting can be readily droppedout of the rear member A of the mold.

It will be noticed that by making the joints F, F, F in the mannerdescribed,

they are not affected by the expansion and contraction of the moldincident to the for mation and removal of the ingot, so that the moldcan be used over and over again without danger of forming undesirablefins.

The under side of the rear mold member A projects a distance below; theunder side of the front mold member B, so that when the mold is restingon a suitable foundation, the under side of the front member B is freeof the support and can be readily swung into an open or a closedposition.

It is understood that when the mold members A and B are closed and themolten metal is poured into the mold, all the strain is taken up by themachined and the interlocked joints, thus relieving the hinge of unduestrain.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. A mold comprising two mold members hingedly connected with each otherat one side, the members being approximately L- shape in cross section,one of the members having an integral bottom, the said members havingjoints at the bottom and sides, the said joints each comprising aright-angled corner on one member engaging a corremember.

right angled corner on one member engag ing a correspondingly shapedrabbet on the other member, the vertical axis of the hinge being forwardof the adjacent joint of the members.

3. A mold, comprising a rear member, a front member, and a hingeconnecting the said members with each other at one side and a distanceforward of the rear member,

, the said members being L-shape in crosssection and the rear memberhaving an integral bottom and a cutout portion at the top.

4. A mold, comprising a rear member, a

front member, and a hinge connecting the said members with each other atone side i and a distance forward of the rear member, the said membersbeing L-shape in cross section and the rear member having an integralbottom and a. cut out portion at the top, the joints of the said membersbeing machined and interlocking.

5. A mold, comprising a rear member, a

front member, and a hinge connecting the said members with each other atone side and a distance forward of the rear member, the said membersbeing L-shape in cross section and the rear member havmg an integralbottom and a cut out portion at the to the joints of the said membersbein and interlocking, and means for ioldin the free ends of the said.members lock in closed position. 1

6. A mold comprising a rear member, a front member and hinges connectingthe said members with each other at one side and at a point forward ofthe rearmember, the said members being approximately L-shape in crosssection and the rear member having an integral forwardly projectingbottom forming the bottom of the mold, and a cut out portion at the top,the lower face of said rear member projecting below the lower face ofmac ined the front member, and clamps for holding 4 the mold members inclosed osition'.

In testimony whereof ave signed my name to this specification in thepresence of two subscribing witnesses.
